Summary
A rare case of renal tuberculosis presented as a large kidney cyst in an elderly woman. Laparoscopic surgery revealed the infection, highlighting an unusual manifestation of this common disease.
Area of Science:
- Nephrology
- Infectious Diseases
- Surgical Pathology
Background:
- Renal tuberculosis (TB) is a significant global health concern, often presenting with nonspecific symptoms.
- While common, TB affecting the kidneys typically manifests as granulomatous inflammation or abscesses, not usually as a cystic lesion.
Purpose of the Study:
- To report an extremely rare presentation of renal tuberculosis mimicking a complicated renal cyst.
- To highlight the importance of considering infectious etiologies in complex renal cystic masses.
Main Methods:
- A 74-year-old female patient presented with fever and left flank pain.
- Imaging revealed a large, complicated left renal cyst with abdominal mass effect.
- Laparoscopic renal cyst unroofing was performed for diagnosis and treatment.
Main Results:
- Histopathological examination of the cyst wall and fluid confirmed renal tuberculosis.
- The patient's symptoms were attributed to the tuberculous cyst.
Conclusions:
- Renal tuberculosis can present atypically as a complicated renal cyst, a very rare clinical scenario.
- Laparoscopic intervention facilitated diagnosis and management of this unusual presentation of renal TB.

01:31Pulmonary Tuberculosis III
Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

01:28Pulmonary Tuberculosis II
Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...

01:29Pulmonary Tuberculosis I
Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

01:26Pulmonary Tuberculosis IV
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

01:27Acute Pyelonephritis I: Introduction
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such as Proteus,...
